A CDC sponsored project for evaluating data on emerging genetic tests.
Fumes in air forming HCl g i Add a few drops to water, test with litmus and silver nitrate solution.
C6H5—NH2 i Dissolve the primary aromatic amine in dilute hydrochloric acid at 5oC and mix with sodium nitrite solution.
Diazonium salts from aliphatic amines decompose rapidly evolving colourless nitrogen. Note 1 Test b i and ii can be used to distinguish aldehydes reaction and ketones no reaction.
Aldehydes are stronger reducing agents than ketones and reduce the metal ion and are oxidised in the process i. Note that aromatic halogen compounds where the X is directly attached to the ring, do NOT readily hydrolyse in this way and no AgX ppt.
Aromatic C—X is a stronger bond than aliphatic C—X. Add dilute nitric acid followed by aqueous silver nitrate solution. Ag2O forms if solution alkaline. Usually a colourless liquid with a pleasant 'odour'. Deep red or purple colour formed. The reaction is also given by acid chlorides and acid anhydrides, and phenols give a purple colour with iron III chloride, so frankly, the test is not that good.
This test is not likely to be expected Iodoform test The formation of CHI3, triiodomethane or old name 'iodoform'. NaOH aq is added to a solution of iodine in potassium iodide solution until most of the colour has gone. The organic compound is warmed with this solution.
A yellow solid is formed with the smell of an antiseptic, CHI3, tri—iodomethane, melting point oC. What is the test for alkenes? How do you test for an alkene functional group? What is the test for unsaturation?

B. Yim In contrast to nucleic acids and proteins, the biosynthesis of glycans is not directly template-driven but, rather, is a result of a complex network of metabolic and enzymatic reactions that are influenced by many factors, including the genetic profile of the cells in which the glycoconjugates are expressed, epigenetics and the extracellular environment.
The Passive Sampler for Organic Vapors collects organic vapors without the use of a pump. The sampler is validated for short-term and eight-hour sampling and hour indoor sampling for some compounds.
